Not exactly sure what should be included here so I will just say I got involved with heli a couple of years ago with a Christmas gift I was given. An air hog havoc. I later found a guy selling a Blade 400 in pieces came with a DX6i and lots of spare parts, along with a Walkera cb100 fixed pitch and a 4 ch all for $ 50. Got the 400 together from watching Tonys vids but being new to ccpm it didn't stay that way long. (Approx 2.5 -3 seconds the first time. The 500 is an amazingly easy fly but does scare folks and is rather pricey to fix if you blink your eyes. Hopefully any problems I encounter can be answered by this resource.
